I play 5 times daily tournaments and 3 times I was to 25. place. Usually I need about 350 battle points to be 25. or better. It was not problem for me when I have characters and this character level during tournament. I take about 300 points by normal play and another 50 points by leveling. But this is too much. I cannot win tournament withought leveling characters.
Usually I can play arount 18 duels. I need to win 14 duels by 25 battle points to have chance be better than 25. But there are players, which win with 1100 battle points. It is impossible withought preparing a lot of characters for leveling and bet battle points by that.
Is not it good idea to reduce battle points by leveling characters? Because IMHO it is not about how good you play now.
Win tournament by colluding with rest league members? Hmm, I don't like this idea, IMHO it is cheating too. It would be nice if there will be tournament about be good in play, not have a lot of friends. For example fixed number of duels, random selection of oponents. And if you have more winning battle points, you fight with better oponent. It would be very nice...
